The difference between Shanghai simple household constant temperature and humidity box and walk-in constant temperature and humidity box
Shanghai Jianhu constant temperature and humidity test chamber can accurately simulate the complex environment of low temperature, high temperature, high temperature and high humidity, and low temperature and low humidity. Reliability testing of products in various industries.
1. The constant temperature and humidity test chamber can accurately simulate the complex natural environment of low temperature, high temperature, high temperature and high humidity, and low temperature and low humidity. Product reliability testing in scientific research units and other industries.
2. Product Features
1. Wide temperature and humidity curve range, standard model can achieve 20% RH;
2. Flow calculation control of refrigerant servo valve. Power saving 40%;
3. The controller's anti-electromagnetic interference has been certified by SGS;
4. Passed ISO-9001 quality certification (Taiwan & Mainland)
5. Temperature and humidity synchronous lifting slope control (IEC68-2-56, 68-2-30), no dripping, no condensation and frost.
3. Types of constant temperature and humidity test chamber
1. The constant temperature and humidity test chamber is also called high and low temperature alternating humidity heat test chamber. The difference is that the name is different, its function, characteristics, principle, structure, purpose and use method are the same.
2. The walk-in constant temperature and humidity room is simply a large constant temperature and humidity test chamber, but it has many differences from the constant temperature and humidity test chamber. The walk-in constant temperature and humidity room is suitable for batch inspection of products or reliability testing of relatively bulky products.
4. Technical characteristics
1. With disk USB recording function, no recorder is required;
2. The temperature and humidity curve range is wide, the standard model can achieve 60% (40 ° C) 20% RH;
3. Flow calculation control of refrigerant servo valve. Power saving 30%;
4. High temperature and high humidity test to prevent condensation and dripping technology industry top
5. The low-temperature working state, the heater does not participate in the work, the PWM technology controls and adjusts the refrigerant flow and flow direction of the refrigeration unit, and the three-way flow adjustment of the refrigeration pipe, cold bypass pipe, and hot bypass pipe realizes the automatic temperature of the studio Constant. This method can reduce energy consumption by 40% under low temperature conditions
6. Passed ISO-9001 quality certification (Taiwan & Mainland)
7. Temperature and humidity synchronous up and down slope control (IEC68-2-56, 68-2-30), no dripping, no condensation5, two types of constant temperatureFive, common points of constant humidity test equipment
1. Both can accurately simulate the complex natural environment of low temperature, high temperature, high temperature and high humidity, low temperature and low humidity, and provide reliability testing for products.
2. The functions, principles and characteristics are the same
6. Difference between constant temperature and humidity test chamber and walk-in constant temperature and humidity room
1. Scope of application: The constant temperature and humidity test chamber is suitable for product sampling or reliability testing of products with relatively small volume. The walk-in constant temperature and humidity room is suitable for batch inspection of products or reliability testing of relatively bulky products.
2. Structure: The constant temperature and humidity test box is generally made of imported SUS304 ﹟ stainless steel mirror panel, and the wall is resistant to high temperature. The outer shell is made of high-quality cold-rolled plate or SUS304 # yarn-textured stainless steel. . The walk-in constant temperature and humidity room generally adopts SUS304 ﹟ stainless steel plate for the inner box and color steel plate for the outer shell.
3. Performance: Constant temperature and humidity test chamber:
4. Appearance: The constant temperature and humidity test chamber generally adopts an integrated type, that is, the refrigeration system, the heating system, the air circulation system, and the waterway system are all installed in the cabinet. . That is, the control system is generally installed outside the box.
5. Production: The walk-in constant temperature and humidity room has a longer production cycle than the constant temperature and humidity test box, and the constant temperature and humidity test box is generally installed and debugged by the manufacturer and can be directly handed over to the customer. It can be used only after being assembled and debugged at the customer's designated place (due to the large volume of the walk-in constant temperature and humidity room, it is generally not transportable and can only be transported to the customer's location after disassembly)
6. Cooling method: The constant temperature and humidity test chamber is generally air-cooled, and the walk-in type is generally water-cooled (requires installation of water tower, water pump, and water pipe).
7. Price: The walk-in constant temperature and humidity room is much higher than the constant temperature and humidity chamber.
8. Power supply: The walk-in constant temperature and humidity room is generally in the three-phase 20KW-50KW, and the constant temperature and humidity testing machine is much smaller.
9. Volume: The walk-in constant temperature and humidity room is relatively larger than the constant temperature and humidity test chamber, and the installation space requirements are also relatively large.
